## The regular Prism

A regular Prism has an regular polygon as base and vertical edges.

The following elements of a regular prism are calculated if two of them are given:

- Edge a
- Altitude h
- Circumradius r
_{u}
- Inradius r
_{i}
- Volume V
- Base B
- Surface S

### Example:

Given:
Eckenzahl n = 6
Edge a = 1
Volume V = 1
Results:
Altitude h = 0,38490018
Circumradius rc = 1
Inradius ri = 0,8660254
Base B = 2,5980762
Surface S = 7,5055535
